This Morgan C-Melody is a saxophone mouthpiece made of 100% pure hard rubber similar to the rubber used to make mouthpieces in the 1920s-1950s. The C-Melody mouthpiece features a large round chamber with low baffle, but unlike its vintage counterparts, this one has very playable tip openings: 4 (.080), 5 (.085), and 6 (.090). This Morgan C-melody mouthpiece is also designed to use modern tenor reeds.
